There are three main sizes of solar panels – 60-cell, 72-cell or 96-cell and the number of panels required for your system will be dependant on your average energy usage in your home. Most solar panels output 250 watts to 400 watts per panel so using this estimation, it can give you an idea of how many panels you will need and the requirements for your system.
An unshaded, South facing roof is best for maximum output however an East or West facing roof would also be suitable for your system. As solar panels are classed as ‘permitted developments’, planning permission isn’t required in the majority of installations and we can advise on any circumstances that may be an exception to this.
